Hello everyone, is there a way for starting a task, if and only if, a sub-workflow has failed ?

Let's say I have a workflow of 3 sequential tasks, and I'd like a 4th task to be ran if, and only if, one of the 3 tasks fails.

but, this is infact supported in the backend through `failure nodes`

but not implemented in flytekit python today

Thanks Ketan ! Out of curiosity, is it in the plan to expose this to the flytekit python ?

so the support is for something like

try:
   task1
    task2
    ….
catch:
     do_something

here is the issue - <https://github.com/flyteorg/flyte/issues/1506>
